LAMP-SHADE.

Specification of Letters Patent.

Application filed April 14, 1915. Serial No. 21,222.

To all whom it may concern f Be it known that I, TETSUSABURO WATA- NABE,a subject of the Emperor of Japan, residing in the city of New York,borough of Manhattan, county and State of New York, have invented acertain new anduseful Lamp-Shade, of which the following is aspecification.

This invention is a lamp shade, and the object of-the invention is toproduce a lamp shade which, when illuminated, produces scenic or coloreffects in motion.-

With the foregoing object in view, the invention embodies, generallyspeaking, an exterior shade or screen of translucent material,exteriorly of which is revolubly mounted a secondary shadeadapted tocarry color or scenic effects. In the .upper open end of the secondaryshade are positione propeller blades which, as the heat rises 'from thelamp, candle, or other source of illumination, are actuated by the heatwaves and thereby revolve the secondary shade, with the result that thepictures or color schemes positioned thereon are projected on the outershade and present a moving effect to the observer.

In the preferred embodiment of the invention, a frame is provided, whichframe is adapted to serve as uni ary means for supporting the exteriorand secondary shades and simultaneously supporting the whole in fixedposition upon the illuminating means. v

Features of the invention andthe advanother than those specified, willbe apparent from the following description taken in conjunction with theaccompanying drawings and appended claims.

In the accompanying drawings, I have illustrated different practicalembodiments of the invention, but the constructions shown therein are tobe understood as illustrative, only, and not as defining the limits ofthe invention.

Figure through a lamp shade of the preferred embodiment of my invention.Fig. 2 is a plan view of the shade-supporting frame, with both theexterior andsecondary shades detached. Fig. 3 is a plan view of thesecondary shade. Fig. 4 is a central, vertical section through amodified form of the invention, and Fig. 5 is a like section through ashade embodying a further modification.

Referring to the drawings,- and more parconstruct of silk, paper,

1 1s a central, vertical section" ticularly Figs. 1, 2 and 3 thereof, Adesignates a frame preferably built upfrom bentwlre, embodying a lowerannulus B, an upper annulus C, and spacing members 0. Annulus C is ofsmaller diameter than annulus B, so that frame A is in substantiallyfrusto-conical form. This frame A, wit 1ts lower annulus B, upperannulus C, and spacing members 0, serves as a direct support for anexterior or outer shade D, which is preferably tubular, frusto-conicalin shape. This exterior shade D I preferably or other translucentmaterial, and said shade is ofsuch size as to completely obscure frameA.

Positioned interiorly of frame A and in the inner upper part thereof isan annulus E, which ,is considerably smaller than annulus C, and ismaintained in fixed relation relative to the frame A by spacing rods e,secured at one of their ends to annulus E and at their opposite ends toannulus B. In this embodiment of the invention, annulus E forms a basisof support for the lamp shade, said annulus being adapted, as shown inFig. '1, to rest upon the upper curved edge of a candle or lamp chimneyF, whereby frame A and the parts carried thereby are supported in fixedposition relative to the source of illumination, herein shown as acandle f.

Secured to, inwardly from, upper end of which is tapered to make a pointcontact for, and form a bearing with, the hub h of a fan or propeller11.. Fan h is circular and has secured to its outer periphery adepending frusto-conical apron H, which operates as a secondary lampshade. Fan k and secondary lamp shade H may be formed of any suitablematerial, but are preferably constructed of mica, or othernon-inflammable material, so as to preclude the lamp shade from catchingfire. It will be manifest that the heat, rising from the illuminatingmeans f, will be forced to pass through the fan or propeller h, and, inso doing, will actuate the same and revolve secondary shade H. Thissecondary shade has formed upon either its inner or outer surface, asdesired, scenic effects or color schemes, and the rays of light from theilluminating means penetrate these scenic efl'ects or color schemes andproject the same upon translucent exterior shade D, with the result andextending upwardly and Patented Apr. 11, 1916.

annulus E is an arm g, the

that motion picture or color effects are produced upon shade D. Ipreferably make shade D of. silk of some pale tint, whereby a mostpleasing efiect is produced.

In the modified form of the invention illustrated in Fig. 4, thestructure is substantially the same, in all of its details, as thatillustrated in Figs. 1, 2 and 3, with the exception that additionalmeans, preferably clamping mechanism, is provided whereby frame A may besupported directly upon the illuminating means. This clamping means isshown in the form of a plurality of resilient arms 2', which are fixedlysecured to the annulus E- and converge downwardly, being adapted, asshown in Fig. 4, to tightly grip the candle, gas fixture, or otherilluminating means f It will be manifest, from the foregoing discussionof the preferred form of my invention and the modified constructiondisclosed, that the device is extremely simple and compact. Moreover,the lamp shade, with all its attachments and supporting means, issupported as a unit upon the illuminating means. E. 9., the whole devicemay be lifted from the illuminating means, to allow of its readycleaning, without dismantling the fixture and without the necessity ofpliers or other tools, and this may be done in a simple and. expeditiousmanner. In other words, in the preferred embodiment of the invention,the whole device may be lifted from the lamp chimney F, whereas, in themodification shown in Fig. 4, the clamping members may be withdrawn torelease the device from the illuminating means. v

In Fig. 5 I have illustrated an electric drop light, embodying aplurality of bulbs. In this embodiment of the invention, a plurality ofbulbs j is mounted on the stem J of a suitable standard J Immediatelybelow bulbs j is positioned a reflector j, the outer end of which isflanged, as at 70, to form a seat for a frusto-conical shaped exteriorshade K. The upper end of stem J of the standard is tapered to form abearing point for a secondary shade L, in the upper end of which ispositioned a fan or propeller Z. Secondary shade L is revolved by therising hot air currents from bulbs j, as hereinbefore described.

Having thus fully described the invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a device of the class described, a frame embodying a lower ringand an upper ring, spacing members intermediate said rings whereby asupport is formed, a main shade mounted on said support, a ringpositioned interiorly of said support, spacing means cooperating withsaid interior ring .ary shade having I and the lower ring of the supportfor maintaining the parts in fixed relation, and means cooperating withsaid interior ring for simultaneously mounting the whole in fixedrelation relative to a source of illumination, in combination with asecondary shade, and means for rotatably mounting the same interiorly ofthe main shade, said secondary shade having propeller blades in itsupper open end, whereby the heat from the illuminating means, risingthrough the secondary shade, actuates the propeller blades and revolvessaid shade.

2. In a device of the class described, a frame embodying a lower ringand an upper ring, spacing members intermediate said rings whereby asupport is formed, a main shade mounted on said support, a ringpositioned interiorly of said support, spacing means cooperating withsaid interior ring and the lower ring of the support for maintaining theparts in fixed relation, and means cooperating with said interior ringfor simultaneously mounting the Whole in fixed relation relative to asource of illumination, in combination with a trunnion mounted on saidframe, and a secondary shade revolubly mounted on said trunnion, saidsecondpropeller blades positioned in its upper open end whereby the heatfrom the illuminating means, rising through the lamp shade, actuates thepropeller blades and revolves said secondary shade on the trunnion ofthe frame.

3. In a device of the class described, the combination of a standard,illuminating means mounted on said standard, a reflector mounted on saidstandard beneath said illuminating means, a main shade supporteddirectly on said reflector, and a secondary shade positioned interiorlyof the main shade and revolubly mounted on said standard, said secondaryshade having a plurality of propeller blades positioned in its upperopen end whereby the heat from the illuminating means actuates saidpropeller blades, thereby rotating the secondary shade.

I. In a device of the class described, the combination of a fixed shade,a secondary shade rotatably mounted within the fixed shade, andconcealed means positioned intermediate the upper and lower edges of thefixed and rotatable shades for supporting said shades upon anilluminating medium, said secondary shade having propeller bladespositioned within its upper end whereby the waves of heat rising fromthe illuminating medium operate upon the secondary shade to rotate thesame.

In testimony whereof I have signed my name to this specification.
